JOHN F. AHRENS, OF BROOKLYN, NEW YORK.

COLLAR BUTTON.

Application filed October To all whom, t may concern.:

Be it known that I, JOHN F. AHRENs, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Collar Button, of which the following is a full, clear, and exact description.

An object of the invention is to provide a button which when closed will be substantially fiat and which will firmly grip the material of the article of clothing to which it is connected, so as to prevent the button from moving around in the buttonhole and also to prevent the possibility of its being lost.

The invention is illustrated in thel drawings, of which Figure 1 is a perspective view of the button with the shank shown in its open position.

Figure 2'is a cross-section through Y'the button showing it in open position in association with a fabric.

Figure 3 is a similar view showing the button in its closed position.

Figure el is a plan view of the button in its closed position.

The form of the invention shown in the drawings is a preferred form, although it is un-derstood that modifications in the construction and arrangement of the parts and in the character of the materials used may be -adopted without departing from the spirit of the invention as set forth in the appended claims.

In its general aspect the invention concerns a button having a base to which a shank is pivotally connected said shank adapted to be associated with the base in such a manner and by the intermediary ofl a resilient plate that it will be firmly held in either its open or closed position. The end of the shank is preferably provided with a head portion which is preferably cupshaped. The shank is of such length that when it lies substantially iiat against the base the end of the head will project only ever so slightly beyond the edge of the base. This projection will permit, however, the linger of the wearer to get beneath the head and move it to its open position when desired. Disposed on the upper surface of the base are prongs which are intended to engage the surface of the fabric with which the fabric is associated and projects slightly thereinto, so that when the button is being 2,' 1925. sei-iai No. 60,083.

wornthe engagement of the fabric with the prongs will tend to prevent the button from rotating. The cup-shaped portion of the headl of the shank is so disposed that it will lie substantially over the prongs when the shank is lying fiat along the base. This will further insure the positive gripping of the fabric by the prongs.

The preferred form of the invention as shown in the drawings comprises a button having a base plate 10. Associated with the base plate is a spring plate 11. Pivotally mounted on the base plate is a shank 12, having' ear portions 13, extending in opposite directions from the lower end of the shank and lying beneath struck up portions 14, associated with the base so as to permit the shank to move pivotally with respect to the base. The shank has on its upper end a head 15, which is preferably cup-shaped, as shown. On the upper surface of the base, opposite the lower end of the shank are formed prongs 16. These may be formed and mounted in any desired .manner not shown. They are so placed on the base that when the shank lies flat along the base the prongs will be covered by the cup-shaped portions of the head 15. As shown in Figure 3 the fabric 17 having a buttonhole 19 therein, is engaged by the button, and the prongs 16 bear against. one side of the fabric, whereas the cup shaped portion of the head bears against the other side. The lower end, 18, of the head, projects slightly beyond the edge of the base 10, so that it can be engaged by the finger of the wearer. The engagement of the fabric by the prongs will prevent the rotation of the button in thebuttonhole. The association of the cupshaped portion of the head with the prongs will improve the grip of the button on the fabric. The fact that the shank is only slightly longer than the base will permit the button to be opened and yet not make it too long.

That I claim is:

1. A collar button which comprises a base, a shank pivoted thereto, a head on said shank, fabric-engaging means on the base adapted to be disposed closely adjacent to the head when the shank lies fiat against the base.

2. A collar button which comprises a base, a shank pivoted thereto, a cup-shaped head on said shank, fabric-engaging prongs on the base, the cup-shaped head adapted to lie over the prongs when the shank is lint; againstthe lmse.

3. A collar hutten which comprises si hase, :i shank pivoted thereto, sp1-ing means for lwlding.;` the shank in its open and closed positions, e cup-shaped heed on seid shank, the length ot' the shank being -sniieient to canse the end of the head to project slightlyT heyond the hase when the shank lies Het, against the huso, Politie-engaging prongs on the hase disposed to lie beneath the enpshnped head when the shank is disposed tint against theA hose.

#1:. A coihir hut-ton which comprises e hase,

l5 :i shank pi'voted thereto, springl ineens for holding the shank in its open :ind closed positions, ineens on the hase to engage the ilizihric to prevent the collar button from turning when in position on the fabric.

A collar hutten which comprises L hase, :i shank pivoted thereto, spring ineens for holding the shank in its open und closed positions, ineens on the hase to engage the itnhric to prevent the Coller hutten from turning` when in position on the fabric and ineens on the shank to Cooperate with the lust-mentioned niezins to hold the collar hutton .in position.
